(\tau_1,\tau_2)^*-Semi Star Generalized Closed Sets in Bitopological Spaces

The aim of this paper is to introduce the concepts of (\tau_1,\tau_2)^*-semi star generalized closed sets, (\tau_1,\tau_2)^*-semi star generalized open sets and study their basic properties in bitopological spaces. Further a new class of generalized continuous maps called (1,2)^*-s^*g continuous maps are introduced and studied their properties in bitopological spaces. Moreover, we investigate the relationships with other continuous functions like (1,2)^*-g continuous maps, (1,2)^*-sg continuous maps and (1,2)^*-gs continuous maps. Also pairwise semi star generalized T_S-spaces is defined.
